Description
The ControlByWeb® X-22S™ is an 8 analog input expansion module designed to add high-resolution analog measurement capability to an X-400™ or X-600M™ controller. Supporting multiple voltage ranges as well as 4–20mA current-loop sensors, the X-22S provides the flexibility needed for a wide variety of industrial and process instrumentation applications.
Engineered for accuracy and reliability, the X-22S is well suited for applications such as tank or bin level monitoring, flow and pressure measurement, and energy or environmental data acquisition. Multiple X-22S modules can be connected via ribbon cable to expand analog input capacity as needed, making it a versatile solution for flexible analog monitoring.
